The Best Semiconductor Of Them All?

Share This Post

Cubic boron arsenide, which handles heat ten times better than silicon, could become the new king of semiconductors, especially in electric vehicles. Despite silicon’s ubiquity as a semiconductor material, it has two weaknesses: its lack of accommodation for electrical particles called “holes” and its poor heat capacity. It’s already being replaced in EV semiconductors by the more heat-conducive silicon carbide, despite being less accommodating to holes. Cubic boron arsenide doesn’t have these weaknesses, so it could easily replace both of these materials once scientists learn how to produce it reliably. Read full article here

On the other hand, Lorenzetti’s “The Allegory of Good and Bad Government” is an example of an aesthetic encounter that successfully encourages us to fear security itself and develop our critical reading skills to help safeguard our democracy.
